You can utilize the VideoReader, implay and VideoWriter functions of MATLAB.
Here is some sample code on how to use these functions:
videoReader = VideoReader('path/to/video/file.mp4');
videoPlayer = implay('path/to/video/file.mp4');
videoWriter = VideoWriter('path/to/save/output.mp4', 'MPEG-4');
Setting equal framerates for VideoWriter instance and implay instance.
videoWriter.FrameRate = videoReader.FrameRate;
open(videoWriter);
Then run a while loop over the video which is to be read using the implay instance and use the writeVideo function to write the file data into the VideoWriter instance.
while hasFrame(videoReader)
% Read the frame
frame = readFrame(videoReader);
% Perform some operations on the read frame
% Write the frame to the video writer
writeVideo(videoWriter, frame);
end
Close the instances you opened using the functions in the first step.
close(videoReader);
close(videoPlayer);
close(videoWriter);
You can check out the MATLAB documentation for these functions to have a better idea about the operations which you could perform on the video you read and the file you write in.
